After installing a patch upgrade, you have the option to revert the fix. You can only
revert the last installed version. If you have installed multiple patch releases, you must
revert them in the reverse order you installed them.

Steps

In the current patch version, choose Revert.

Restart affected services.

When you perform a Patch Express Upgrade of a service, a dependent service may
stop and require a manual restart. For example, a patch Express Upgrade of HDFS could
stop HBase. In such cases, you must manually re-start HBase using the Ambari Web UI >
Service Actions menu.
